Sounds like the ignitor is not picking up the flame. After ignition and approximately 10 seconds of burning, the ignitor turns into a flame rectifier. The control module can be bad or, if the...
With a load on the unit, the new compressor will bring back oil in the evap. So, adjust as needed once it has run awhile. Ensure the CCH is working. If the unit is setup with pumpdown on it, cycling...
An MP581 can be used stand alone.
You will have to control it by mixed air temp., ensuring that the mixed air sensor is not situated close to the heating coil (if it has one). Also, you will have to make your minimum 0% when...
TR200 (Danfoss Drive) has the filtering in it that prevents bearing fluting. Most other brands it is an option you have to order seperately.
You defenitely should put drives on your fans. Then use a temp controller to ramp the fans speed up or down to control water temp. Your chiller will defenitely be happier with a steady water temp...
I agree with Lafittejdubb on the leak through. Have seen it a few times myself. Also, did they load this end of the server room more so than the rest? Have seen that a few times as well.
The valves are the same. They have a cap with an o-ring in it instead of a handle. You open with a crescent wrench and then put the cap on. My question is, if there is no flange leak, then why not...
We have had several leak. The problem is that they do not want to change them proactively. You have to wait until they leak, knowing that sooner or later they will.
sounds like it doesn't have enough voltage to pull in but has enough to stay in. Is it using a conventional stat? If so, how long a wire run and what gauge t-stat wire.
This is actually an RAUBC by the serial number. See if the attached help.
Set up a discharge reset off of the average space temp.
Hope these help
Possible pressure issues. Is there anything on floors 2 and 3 that would warrant not having return come back( i.e.labs)? Otherwise, sounds like a FUBAR.
is the space in a negative pressure?
If it is the stat with the numbers (1,2,3,etc) instead of Y,H,G then it dictates mode by resistance. It cannot be jumped out at the stat if that type.
Read this sequence and see if it helps
go in thorugh HI and enter test mode there. Wish I was in Texas. 5 degrees this morning in KY!! YUCK!
you're thinking of a voyager.
Please let us know what they find.
VFDs on AHUs or pumps.
with the economizer disabled, how would you ventilate for high CO2??
